The atomic number is the same for the all isotopes of a chemical element.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
The different isotopes have different atomic mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
Isotopes of an element have different numbers of neutrons than normally expected. If you add one neutron, you will also add one a.m.u.
atomic masses
Isotopes. They differ in the number of neutrons in the nucleus.

the atomic number
atomic masses
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Isotopes. They differ in the number of neutrons in the nucleus.
Isotopes are atoms of an element having different number of electrons.
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
